ERDS DISCOVERED INOPERABLE
"...This report is being made pursuant to 10 CFR 50.72(b)(3)(xiii) and Exelon Reportability Manual SAF 1.10. At 2100 hours on 11/12/01, it was discovered that the Emergency Response Data System (ERDS) was not operational. This system provides a data link between the LaSalle onsite computer system and the NRC Headquarters Operational Center when activated during emergency situations. The ERDS system was restored to an operable status at 2320 hours on 11/12/01 after resolving a computer system software issue. The NRC resident inspector has been notified of this event."
The discovery was made while conducting training of a new candidate.

INDICATION OF PRESSURE BOUNDARY LEAKAGE DISCOVERED DURING VISUAL INSPECTION OF HEAD
The licensee was conducting visual inspection of the reactor vessel control rod drive mechanism (CRDM) nozzles in response to the NRC Bulletin 2001-01. They discovered indications of leakage evidenced by minor boric acid buildup around 4 CRDM nozzles. There is potential for 3 additional nozzles leaking that will require further inspections. Additional inspections and repairs will be conducted in accordance with NRC Bulletin 2001-01. The plant will remain at or below Cold Shutdown until repairs are completed.
The licensee notified the NRC Resident Inspector.
